不同位置的金属微粒对GIS隔离开关电场的影响分析

Gaoya dianqi
隔离开关作为GIS的重要组成部件，如果有金属微粒等异物存在，将对隔离开关的绝缘性能产生影响。因此，计算GIS隔离开关带金属微粒时的电场分布至关重要。文中采用三维有限元分析计算方法对隔离开关无金属微粒和不同位置带金属微粒两种工况进行了电场强度计算。对比计算结果可知，屏蔽罩表面附着金属微粒所产生的电场畸变最为严重，绝缘拉杆表面和SF6气体中的金属微粒也会大大增加场强值，导致隔离开关极易放电。基于电场分析所得的计算结果，文中对隔离开关的生产和安装提出了合理的建议。

不同材料的隧道电缆支架适用性对比研究

Gaoya dianqi
输电电缆线路运行电流较大，电缆支架涡流损耗和温升的问题被广泛关注，急需寻找一种损耗小、温升低、经济性能良好的支架材料。文中采用多物理场耦合的有限元分步仿真计算方法对220 kV电缆线路的钢、不锈钢和新型玄武岩复合材料支架的涡流损耗和温升进行计算。首先在频域下计算涡流损耗，之后再以涡流损耗作为热源，在瞬态下进行电磁场—温度场—流体场三场耦合计算，从而计算出支架温度分布。该方法在保证计算精度的前提下极大降低了计算的复杂度。计算结果表明：钢支架涡流损耗远大于不锈钢支架和玄武岩支架的涡流损耗。电缆电流为1 ...
